2 goes into all the terms so;

2(-2x² + 7x - 3) now you could factor it:

2(-2x - 1)(x + 3)

Prove the following identities : i) tan a + cot a = cosec a sec a

inysia [295]

Step-by-step explanation:

$\tan \alpha + \cot\alpha = \dfrac{\sin \alpha}{\cos \alpha} +\dfrac{\cos \alpha}{\sin \alpha}$

$=\dfrac{\sin^2\alpha + \cos^2\alpha}{\sin\alpha\cos\alpha}=\dfrac{1}{\sin\alpha\cos\alpha}$

$=\left(\dfrac{1}{\sin\alpha}\right)\!\left(\dfrac{1}{\cos\alpha}\right)=\csc \alpha \sec\alpha$

Answer:

$8x^3+28x^2-16x$

Step-by-step explanation:

Volume of rectangular prism: $l*b*h$ (l = length, b = breadth, h = height.)

Volume of rectangular prism:

$(x+4)*(2x-1)*4x$

$4x\left(x+4\right)\left(2x-1\right)$

Expand the two brackets using FOIL:

$4x(x* \:2x+x\left(-1\right)+4* \:2x+4\left(-1\right))$

$4x\left(2x^2+7x-4\right)$

Expand:

$4x* \:2x^2+4x* \:7x+4x\left(-4\right)$

$8x^3+28x^2-16x$
